Inter- and Intra-Observer Variability of the Volume of Cervical Ossification of the Posterior Longitudinal Ligament Using Medical Image Processing Software

摘要

ObjectiveComputed tomography (CT)-based method of three dimensional (3D) analysis (MIMICS^®, Materialise, Leuven, Belgium) is reported as very useful software for evaluation of OPLL, but its reliability and reproducibility are obscure. This study was conducted to evaluate the accuracy of MIMICS^® system, and inter- and intra-observer reliability in the measurement of OPLL.
